What is Answer Engine Optimisation?
The complete guide for business owners — what AEO actually is, how it differs from SEO, and the signals AI platforms read before they recommend anyone.
Answer Engine Optimisation (AEO) is the practice of structuring your content, brand information and digital presence so that AI platforms — ChatGPT, Google AI Overviews, Gemini, Claude, Perplexity — cite and recommend your business when customers ask questions. SEO gets you ranked. AEO gets you recommended.
Search changed. The answer replaced the list.
For twenty years, being found meant ranking in a list of ten blue links. Now a growing share of buying decisions start with a question put to an AI assistant — and the assistant answers with one, two, maybe three recommendations. There is no page two. If your business isn't in the answer, you were never in the running.
AEO is the discipline of earning that spot. It treats every AI platform as an "answer engine" and asks one question: when someone describes the problem you solve, does the machine say your name?
How AEO differs from SEO
They're complementary, not competing. Strong SEO gives AI models crawlable, credible material to learn from — AEO makes sure what they learn is accurate, consistent and quotable. Doing AEO without SEO foundations is building on sand; doing SEO without AEO is optimising for a shrinking share of attention.
The five signals answer engines read
Entity clarity
Does the machine know exactly who you are — one consistent name, category, location and offer across your site, directories, maps and social profiles?
Structured data
Schema markup (Organization, Service, FAQ, Review) turns your pages from prose into facts a machine can quote with confidence.
Third-party citations
AI weighs what others say about you more than what you say about yourself. Industry press, directories, associations and reviews are the map of trust it reads.
Answer-shaped content
Pages that pose the real question and answer it directly, in the first paragraph, get lifted into AI answers. Pages that bury the answer get skipped.
Reputation signals
Review volume, recency and rating — plus how you respond — feed both local AI answers and the general trust score models assign your brand.
How to measure progress
AEO has its own scoreboard. Instead of rank positions, you track: citation share (how often AI answers cite you vs competitors for your key questions), answer accuracy (does AI describe your business correctly), entity consistency (does every platform agree on who you are), and AI-referred traffic and enquiries. We package these into a single Visibility Score so you can watch it move.
Where to start
Ask ChatGPT, Gemini and Perplexity the questions your customers ask — "best [what you do] in [your city]", "who should I hire for [problem]". If you're absent or described incorrectly, start with the foundations: consistent business details everywhere, schema markup on every page, answer-shaped content, and a deliberate program of earning mentions on sources AI trusts.

Common questions
What is Answer Engine Optimisation?
AEO is the practice of structuring your content, brand information and digital presence so AI platforms like ChatGPT, Google AI Overviews, Gemini and Perplexity cite and recommend your business when people ask questions.
Is AEO different from SEO?
Yes. SEO earns rankings in a list of links; AEO earns citations inside AI-generated answers. They share foundations, but AEO adds entity clarity, structured data, third-party citations and answer-shaped content.
How long does AEO take to work?
Foundational fixes — schema, entity consistency, answer-shaped pages — can influence AI answers within weeks. Authority built through citations and reviews compounds over three to six months.
Playbooks by industry
AEO looks different depending on what you sell. Each playbook works through the real questions in one industry and the fixes that move the answer.
